POST-OPERATIVE BANDAGE Filed March 25, 1950 INVENTOR 561M578 BY a ATTNEY Patented July 15, 1952 UNITED STATES PATENT OFFICE POST-OPERATIVEBANDAGE Edmund F. Buryan, Westchester County, N. Y.

Application March 25, 1950, Serial No. 151,915

The present invention relates to a special bandage designed particularlyfor post-operative use following surgery in the anus or vagina.

Insofar as I am aware, there is no fully satisfactory bandage suitableor especially adapted for use after hemorrhoidectomies and otheroperations and which are insertable into, and removable from, bodycavities without a great deal of discomfort and other disadvantageouseffect.

It is, therefore, an object of this invention to provide for the firsttime a special construction of bandage which overcomes the drawbacksmentioned above and which has new features and characteristics notheretofore available.

Another object of the invention resides in the provision of a tubular orcylindrical bandage in which one portion is drawn through another so asto provide, in effect, a double bandage which can be withdrawn from abody cavity while decreasing its diameter thereby facilitating removaland avoiding pain and disturbance of healing incisions or the like.

A further object of the invention resides in a bandage of the characterreferred to which is impregnated and/or coated with special substancesfor therapeutic and antiseptic purposes.

Other and further objects and advantages will be understood andappreciated by those skilled in this art or will be apparent or pointedout hereinafter.

In the accompanying drawing wherein I have illustrated a preferredembodiment of the invention:

Figure 1 is a perspective view of a bandage responding to my invention;

Figure 2 is a longitudinal medial section through Figure 1 and Figure 3is an end view looking from right to left in Figure 1.

Referring now to my bandage in detail in conjunction with the drawing,numeral indicates a tubular or cylindrical outer portion which, as willbe appreciated from Figure 2, merges with and forms a part of asimilarly shaped inner bandage portion ll. As shown in the drawings, theouter bandage portion In is inturned at one end and drawn through itselfso as to form a double or composite bandage having the structure andarrangement which is clear from Figure 2. This can readily beaccomplished by forming a tubular bandage of the desired externaldimensions and then somewhat compressing one end thereof and drawing itthrough the opening I2 until it projects slightly therefrom to provide aterminal portion which can be read- 5 Claims. (Cl. 128-156) ily graspedby hand or by forceps for the purpose to be hereinafter described. Theinner bandage portion ll becomes reduced in diameter and its centralopenings l3 becomes a channel'or passageway, which has various uses,such as for drainage, for the insertion of a speculum, otherinstruments, etc.

The material of the bandage is preferably an absorbent cotton or othersoft, pliant, cellulosic material such as cellucotton, gauze, absorbentpaper and the like. The material of the bandage must be soft enough toavoid injury and yet have enough body to substantially retain its shapeduring use. It also must be sterilizable without undue deterioration. Itis, of course, discarded after a single use.

In addition, the bandage material may be impregnated and/or coated witha variety of substances for special purposes; for example, to retardabsorption and consequent coagulation of blood within the fibrousbandage material, the surfaces thereof are impregnated or coated with aplastic base material or shellac, which provides a smooth but flexiblesemi-impervious or impervious surface. A similar effect is obtained bysurfacing the bandage material with cellophane or other similarmaterial. Particular therapeutic and analeptic results can be producedby providing the bandage material with a thin, outer layer of fibrinfilm or fibrin foam and the bandage may furthermore be renderedbacteriostatic or bactericidal by impregnation with an antibiotic orother chemo-therapeutic agent such as sulfonamide, penicillin,streptomycin or a quaternary ammonium compound, such as analkyldimethyl-benzyl-ammonium chloride. Various combinations ofbacteriostatic and bactericidal agents may also be employed. In afurther form of the invention, the bandage material is coated on thosesurfaces which come into contact with one another with a lubricant suchas a mineral or vegetable, natural or synthetic oil, fat or wax, orother innocuous material having lubricating properties.

In use, a bandage constructed in accordance with the present inventionand as illustrated in Figure 1 is inserted into the body cavity at theappropriate time and allowed to remain therein until the physician,attendant or technician desires to have it removed, at which time theprojecting end of the inner portion l l of the bandage is grasped withthe fingers or by means of forceps or other suitable instrument andgradually and steadily pulled out. This action causes the opposite endof the bandage to be somewhat Particularly in connection with theremoval of my new bandage from the anal canal subsequent to ahemorrhoidectomy, my bandage finds par ticular utility and application.Under ordinary circumstances the removal of such a bandage after such anoperation is extremely painful but with my new bandage and itsoperation.on the;

principle of decreasing diameter as it is with drawn, there is lessdiscomfort.

The foregoing is intended as illustrative and not as limitativesinceother and further modifications may be made without departing from; theinvention as defined-by'the appended claims;

I claim:

1.;A post-operative bandage adapted for in-- sertion into a body cavityand to be-withdrawn. therefrom while decreasing the diameter of thebandage comprising inner'and outer soft, pliant portions of tubularcellulosic material'of which the'inner-portion'is normally inturned anddisposed'within' the outer portionand is unitarily connected thereto atone end.

2.1Abandage as defined by claim 1, which-is composedof an initiallytubular-shape one end. ofhwhich-has been-bent in upon itself and "drawnthrough the opening thereof-until it'forms an inner portion within anouterportion the inner portion-projecting slightly beyond the outerportion ,to; provide a terminal portion for reducing.

3. A bandage in accordance with claim 2, in which the outer portion hasa bore which is normally only slightly larger than the inner portion andthe inner portion has a small bore which acts as a passageway throughthe entire bandage.

4. A bandage in accordance with claim 3, in which the passageway throughthe bandage is small in diameter compared to the diameter of the bandageand the thickness of the inner'bandage portion.

5. A post-operative bandage adapted to be inserted in the anal canalafter hemorrhoidectomy and to'be withdrawn therefrom while decreasingthe diameter of the bandage which comprises inner-and outer tubularportions of soft, pliant, cellulosic material,..the inner tubularportion being disposed in the bore of the outer tubular portion andhaving one end thereof projecting therebeyond and being connected at itsother end to said outer tubular portion, the bandage as a whole beingcharacterized by having an axialpassage way therethrough. 4
